Hello,
In media/platform/mxc/capture/v4l2-int-device.h, there is only one input format defined : V4L2_IF_TYPE_BT656.
Does this means that the only timing mode for CSI is BT.656 mode when using the imx6q-v4l2-capture IPU driver?
How to deal with a sensor camera connected to CSI in gated mode ie with HSync VSync?
Note : I use the terms BT.656 mode and gated mode as described into the IMX6DQRM
Thank you
I found my answer : into mxc_v4l2_capture.c, bt656.clock_curr != 0 configures CSI in gated mode.
yes, if you want to use gated mode, you can modify this source code, if you want to use bt656 progressive mode, you can change the "INTERLACED" to "PROGRESSIVE"
if (ifparm.u.bt656.clock_curr == 0)
csi_param.clk_mode = IPU_CSI_CLK_MODE_CCIR656_INTERLACED;
else
csi_param.clk_mode = IPU_CSI_CLK_MODE_GATED_CLK;
"How to deal with a sensor camera connected to CSI in gated mode ie with HSync VSync?" what mode do you need? bt656 mode or gated mode? do you need to capture bt656 in gated mode?? de-interlacing?
